Subject: [PATCH] ARM: modify mfp-w90p910.c and add mfp.h to w90x900 platform
Dear Russell,
To rename, modify mfp-w90p910.c and add mfp.h for
'extern', duo to some drivers need the functions of
mfp.c frequently, so it is better that inlcuding
this header file in driver c file directly rather
than for the 'extern' to have to create specific
driver header file.
